This question stirred the country to its depths in 1799. Great Britain applied to our government for the extradition of a seaman who claimed to be an American citizen and was charged with committing murder on a British man-of-war. He was arrested in South Carolina, under a warrant from the District Judge, and lodged in jail. There was a treaty of extradition between the two powers covering cases of murder, but no particular machinery had been provided for regulating the surrender. The British consul asked the judge who had made the commitment to order his delivery to him. The judge doubted his power to do so. Thereupon the Secretary of State, by authority of the President, wrote him that the President advised and requested him to make the surrender, if satisfied with the proofs of criminality, as he (the President) was of opinion that any crime committed on a man-of-war was committed within the territory of the power to which it belonged. The judge complied with this request, after a public hearing on a writ of _habeas corpus_, under which he ordered the man in question to be brought before him, and in the course of it this letter was shown to counsel on both sides. The surrender became at once the subject of heated debates in Congress, but the President's course was ably and conclusively defended by Marshall on the floor of the House,[Footnote: United States _v._ Nash _alias_ Robins, Bee's Reports, 266; Robbins' Case, Wharton's State Trials, 392.] and the course pursued has since been followed in substance by our extradition statutes.[Footnote: United States Revised Statutes, Secs. 5270, 5272.] These provide for a hearing of a judicial character, and then, if that results in a determination that a surrender should be made, it may be ordered on a warrant from the State Department. On the other hand, the peculiar provision of the Constitution of the United States which makes treaties the supreme law of the land calls upon the courts to enforce them according to whatever interpretation they may conclude to give them, even if it should differ from that adopted by the President or the State Department. If a treaty prescribes a rule by which the rights of private individuals are to be determined, and those rights are such as can be appropriately made the subject of a lawsuit, the court before which it may be brought has as full authority to construe the treaty as it would have to construe an act of Congress, were the matter in controversy one of a statutory nature. They cannot be appropriately made the subject of a lawsuit so long as the questions involved are under active consideration in the course of diplomatic negotiation and pending for decision before the President. Let him, however, once make his decision and the doors of the court fly open.
